• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ty nang ra hoi. hieu ((ve cam) or (va cam)) xuc ban thanh ((le chat) OR (le nhat)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty nang ra hoi. hieu ((ve cam) OR (va cam)) xuc ban thanh ((le chat) OR (le nhat)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty nang ra hoi. hieu ((ve cam) or (va cam)) xuc ban thanh ((le chat) OR (le nhat)) triet".
• Adding a wildcard symbol may retrieve word variants: vu sach ty nang ra hoi. hieu ((ve cam) or (va cam)) xuc ban thanh ((le chat) OR (le nhat)) triet*.
